Sprint HTC One M8 updated with Android 4.4.3 and Wi-Fi calling

The HTC One M8 on Sprint is now receiving an update to Android 4.4.3 KitKat. While Android 4.4.3 brings some under-the-hood changes, nothing much visually changes on the One M8. What is new, however, is the addition of Wi-Fi calling on the Sprint M8.

Sprint debuted Wi-Fi calling earlier this year on a few devices and has been steadily expanding the roll-out since. In addition to gaining support for Wi-Fi calling, the Sprint HTC One M8 now sports an HD Voice icon (how's that for an overwhelming visual change?).

The user-facing changes in Android 4.4.3 are minor, but M8 owners will benefit from the latest bug fixes and performance tweaks in this updated version of Android. Sprint HTC One M8 owners, let us know how the update's treating you!
